The minimum surface area of the cube is (96) cm2
The length of the cube is 4cm
The surface area is 4x4x6 = 96 square centimeters

There are 12 small cubes with the edge length of 1cm. The cuboid has a () middle pendulum method, in which the largest surface area is () cm and the smallest is () cm

12=1×1×12=1×2×6=1×3×4=2×2×3
There are four kinds of pendulum
Maximum surface area: 1 × 1 × 2 + 1 × 12 × 4 = 50 square centimeter
The smallest surface area: 2 × 2 × 2 + 2 × 3 × 4 = 32 square cm
